7. Switch the A/M Knob into automatic and begin paving. Check
the depth of mat at centerline and verify joint matches at lip of
gutter. After compaction, make the necessary adjustments.
8. To pave the other side of the road, position the left tracker over
the lip of the gutter and place the right tracker over the new mat
(Figure 6-18).

9. Survey the control box on-grade and set the displays to read the
depth of asphalt to be laid (see Figure 6-17 on page 6-17). Put the
control box in automatic mode and begin paving. Check to make
sure joints match after compaction.
TIP
If the road width varies, it is easier to keep the
tracker over the gutter if the tracker is mounted to
the extension on the paver.
